Mechanical Properties and Failure Behavior of 3D-SiC/SiC Composites with Different Interphases.

Continuous silicon carbide fiber-reinforced silicon carbide ceramic matrix composites (SiC/SiC) are promising as thermal structural materials. In this work, the microstructure and static mechanical properties of 3D-SiC/SiC with PyC, SiC, and PyC/SiC and without an interface prepared via polymer infiltration and pyrolysis (PIP) were investigated systematically in this paper. The results show that the microstructure and static mechanical properties of SiC/SiC with an interphase layer were superior to the composites without an interlayer, and the interface debondings are existing in the composite without an interphase, resulting in a weak interface bonding.

Study On Potential Factors Of Patient Satisfaction: Based On Exploratory Factor Analysis.

Objective: To explore the potential common factors of patient satisfaction and the influencing factor of it.

Methods: A questionnaire survey was organized and 2626 valid answers were obtained. Through correlation analysis and exploratory factor analysis, the potential factors of patient satisfaction were extracted.

What is the most important factor affecting patient satisfaction - a study based on gamma coefficient.

To analyze the influencing factors of patients satisfaction and find out the key factors, so as to provide suggestions for improving health policy. A questionnaire survey was conducted in Wuhan China. A total of 2,719 questionnaires were collected and 2,626 valid answer sheets were obtained.
